The day-to-day advancement in this field made a direction for growing low-power, low-cost, along with multi functioning of the sensors. This collective formation of the system with motes or sensors is Wireless Sensor Network (WSN). WSNs follow the principle of ”EAAs” stands for Everyone, Anywhere, Anytime. The nodes in the network have certain limitations in t erms of memory, power, etc. Clustering the nodes in the network is an efficient and most preferable technique to address the problem of better performance of the wireless sensor networks. In this work, we provide a re-modified approach for cluster head selection for the transmission of data between nodes, cluster heads, and mote with a low packet loss ratio. The Statistical results of the two existing approaches and the pro- posed approach are compared for 100 iterations and shown in results. The time complexity of the proposed approach is also calculated. Keywords: Wireless Sensor Networks, LEACH, Cluster Head, Network Lifetime, Energy Efficiency. 1. INTRODUCTION The sensor network is a category of networks with nodes termed as specks, sensors or motes . This collective formation of the network, with nodes referred to as wireless sensor networks(WSNs). Figure. 1. Wireless sensor networks are presently very famous and gained its recognition extra than a decade, and it plays a vital role in the formation of the internet of things (IoT) [1] and this [2] leads a direction for digitization. The wsn is setting its identity in each useful resource in each area in which there may be a danger of improvisation. The application taxonomy of wsns [3]have broadly classified into monitoring, monitoring, and controlling [4],[5],[6],[7]. A huge range of capability services to navy, Safety, transportation, enterprise, technology, civil infrastructure, domestic, agriculture, industrial aspects, etc. [8],[9],[10],[11]. Commonly, a sensor node is a form of mini computing with the extra in-built functionality of sensing [12], [13]. Wireless sensor networks have several benefits, which include small in size, and expenses are tons more low priced when human intervention is extraordinarily hard. The most critical benefit of these sensor networks is that node area may be modified unexpectedly without any battle of rewiring and may be configurable to any topology like mesh, tree, star, and so forth. Even as it’s far a promising place in educational, financial and alertness-oriented growth, however, it has many challenges. The operational demanding situations of wireless sensor networks are low electricity efficiency usage of nodes in the system, restricted battery strength due to which less com- putation and garage capability of the node, low bandwidth with mild or high electricity costs for the duration of communication in the order. The mistakes are enormous in wireless networks, due to which the nodes are right away errors-inclined, noisy measurements because of which node failure predicted [14]. Routing is one of the options in wireless sensor networks to clear up the limitations of high network lifetime and much less node energy utilization within the network [15],[16],[17],[18]. The routing protocols are categorized by means of depending upon the mode of functioning of nodes, a form of application specific, kind of network structure, And based totally at the node participation of node. The energy-efficient routing protocols are categorized into flat routing protocol [19],[20], [21] and a hierarchical based routing protocol [22],[23]. This research is motivated to provide a better way to select a head node from the node group termed as a cluster. We modified the head node selection by using a precise equation and making sure that data item transmission among nodes and sink are much better when compared with conventional LEACH and one of the Improved LEACH, making sure of a better lifetime of the network along with minimizing packet loss during the respective transmissions. The process is
